A team of scientists in Thailand has recently developed an innovative oro-nasal film spray that contains curcumin. This spray has shown potential antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses, according to a study published in the Virology Journal.
SARS-CoV-2 and influenza viruses are responsible for respiratory infections that can be particularly severe in older individuals and those with weakened immune systems. As a result, finding effective treatments and preventive measures is crucial.
Curcumin, a bioactive compound derived from plants, has long been known for its various health benefits, including its antioxidant, anti-inflammatory, anticancer, and antimicrobial properties. In this study, scientists aimed to assess the antiviral and immune-boosting effects of a curcumin-containing film spray.
The researchers tested an oro-nasal film spray containing curcumin against SARS-CoV-2, as well as different types of influenza viruses, including A/H1N1, A/H3N2, and B. They found that the spray exhibited antiviral activity against all tested viruses, with the highest inhibitory activity observed against SARS-CoV-2.
Moreover, the curcumin film spray was found to enhance the production of antimicrobial peptides and reduce the secretion of certain inflammatory markers in oral keratinocytes. This suggests that the spray not only has antiviral effects but also boosts mucosal innate immunity.
Importantly, the curcumin formulation used in the film spray remained stable throughout the study, with no observed changes in its physical properties. Furthermore, the spray did not show any cytotoxic effects at therapeutic doses, indicating its safety.
Overall, the findings of this study highlight the potential of this curcumin film spray as a preventive measure against viral infections. Its ability to inhibit viral entry into host cells, enhance mucosal immunity, and reduce disease severity make it a promising candidate for further development and evaluation.
